I bought this battery to replace the original, that ran my Roomba 570 well for almost three years. It started out really well, but has failed after only nine months. Unlike the original battery, it did not respond to the reset procedure. iRobot will not stand behind it after six months.

I purchased the current battery directly from iRobot on 03/28/12. I used it in the Roomba about twice a week. It started out doing fine, lasting almost two hours, but now, after about half an hour, it's calling it quits. I figure that's about 170 uses, or maybe 100 complete charge/discharge cycles. Kind of disappointing. I would hope iRobot would make a lithium polymer battery drop-in replacement for this expensive and not too powerful nickel metal hydride one.

Parts are very expensive and don't last long. I bought the currently battery not that long ago (at least the third one I've bought and maybe more). It's been kept charged and not used that much, but it is totally discharged within two or three minutes. Until I break down and buy yet another battery, my robot is useless.

My son, a Marine, bought me my Roomba before he deployed leaving his Siberian Husky for me to love on in his absence. The Roomba has been a life saver with all the shedding I have dealt with! I do have to empty and clean it probably more than someone without a dog but that is small potatoes to me. My first Roomba quit working after a few months and the company replaced it with no hesitation. I remain impressed with the service they provided. My Roomba is 4 years old and this is my first battery replacement. This is a quality product from a quality company. Oh, son is safe after 3 deploys and I have the dog...and my faithful Roomba!

I like "Marie". She is doing well. The Problem is the battery. In the beginning it's working good, recharging well. But very soon it's not recharging anymore and Marie is only working for few minutes instead of the 2-3 hours from the beginning. It's a pity.

SO I purchased this for my mom after her original battery went bad after leaving the Irobot off the charger. I was sceptical because of the negative reviews but she loves it and says it runs longer than she needs it to using doing the living room, dining, and 2-3 bedrooms.

I love my roomba. Vacuuming is the worst thing for your back and after taking care of my husband who was disabled in Viet Nam, I have back problems. Our daughter gave me mine 5 or 6 years ago. I am still using the original battery but it needs a new one. I couldn't ask for anything better than my roomba. I actually have two both the same age so they clean the whole house at one time.

We use our iRobot to clean our large master bedroom with wood floors. I have has to change the battery only once in the four years we have owned this vac.I have had to replace some smaller parts this are just going to break. I am surprised that this thing keeps going. But it does.

We love our Roombas, but the battery life is short. I continue to buy batteries each each year for our Roombas. The battery when new will go about one hour or so. After about 6 months the battery just dies in about a half hour or less after a full charge. Please research a better battery??
